Ingredients

• 1 tablespoon olive oil – for sautéing.
• 1 medium yellow onion, diced – about 1 cup.
• 3 cloves garlic, minced – fresh is best.
• 1 pound boneless, skinless chicken breasts – about 2 medium breasts. You can also use thighs for more flavor.
• 4 cups low-sodium chicken broth – gives you control over saltiness.
• 1 (15-ounce) can pumpkin puree – not pumpkin pie filling. Pure pumpkin only.
• 1 cup whole milk – or 2% for a lighter version.
• 1/2 cup heavy cream – optional but adds extra richness. You can use all milk if preferred.
• 4 ounces cream cheese, softened – cut into cubes so it melts smoothly.
• 1 cup freshly grated Parmesan cheese – about 3 ounces. Pre-grated won’t melt as well.
• 1 teaspoon dried sage – or 1 tablespoon fresh sage, chopped.
• 1/2 teaspoon dried thyme – complements the pumpkin beautifully.
• 1/4 teaspoon ground nutmeg – a little goes a long way. Skip if you’re not a fan.
• Salt and black pepper – to taste.
• 8 lasagna noodles, broken into 2-inch pieces – about 6 ounces. Use gluten-free if needed.
• Fresh parsley, chopped – for garnish, optional.
• Extra Parmesan – for serving.

Optional Substitutions

• Chicken: Replace with 1.5 cups of cooked shredded rotisserie chicken to save time. Add it in step 5 instead of cooking raw chicken.
• Milk: Use unsweetened almond milk or oat milk for a dairy-light version. The soup will be less creamy but still delicious.
• Cream Cheese: Swap with 1/2 cup Greek yogurt (full-fat) stirred in at the end. Don’t boil after adding to prevent curdling.
• Pumpkin: Butternut squash puree works perfectly. Steam and blend a medium squash until smooth.
• Lasagna Noodles: Use any short pasta like rigatoni, fusilli, or broken fettuccine. Adjust cooking time as needed.
• Broth: Vegetable broth keeps it vegetarian-friendly.
• Nutmeg: Omit or use a pinch of cinnamon or allspice for a different warm spice note.
• Cheese: Pecorino Romano can replace Parmesan for a sharper flavor.

Instructions

1. Prep all ingredients: Dice the onion, mince garlic, and cut the cream cheese into small cubes so it melts evenly. Break the lasagna noodles into pieces about 2 inches long.
2. Sauté aromatics: Heat olive oil in a large pot or Dutch oven over medium heat. Add the diced onion and cook until soft, about 4 minutes. Add the garlic and cook for 1 minute more until fragrant.
3. Cook the chicken: Place the chicken breasts in the pot. Season with a pinch of salt and pepper. Sear for 3-4 minutes per side until golden but not cooked through. Remove to a plate and set aside. (It will finish cooking in the soup.)
4. Build the base: Pour in the chicken broth and pumpkin puree. Whisk until smooth. Add the milk, cream (if using), cream cheese, Parmesan, sage, thyme, and nutmeg. Stir constantly until the cream cheese is fully melted and the sauce is smooth, about 3-4 minutes.
5. Simmer the soup: Bring the soup to a gentle boil, then reduce the heat to low. Return the chicken to the pot along with any juices. Cover and let simmer for 15 minutes, or until the chicken is cooked through (internal temperature 165°F).
6. Shred the chicken: Using tongs, transfer the chicken to a cutting board. Shred with two forks or dice into bite-sized pieces. Return the chicken to the pot.
7. Cook the noodles: Add the broken lasagna noodles to the soup. Stir well. Increase heat to medium and cook, uncovered, for 8-10 minutes, stirring occasionally, until the noodles are tender but not mushy. The soup will thicken as the noodles cook.
8. Final seasoning: Taste and add salt and pepper as needed. Keep in mind the Parmesan is salty, so go easy at first. If the soup is too thick, stir in a splash of broth or milk.
9. Rest and serve: Remove from heat. Let the soup sit for 5 minutes—it will continue to thicken. Ladle into bowls, garnish with parsley and extra Parmesan. Enjoy!

Pro Tips

• Don't overcook the noodles: Lasagna noodles cook faster than you think. Start checking at 7 minutes for al dente. They will soften slightly as the soup sits.
• Cut cream cheese into small cubes: Cold cream cheese can clump. Let it sit at room temp for 15 minutes, then cube it for seamless melting.
• Use freshly grated Parmesan: Pre-shredded contains anti-caking agents that prevent smooth melting. Grating it yourself takes two minutes and makes a huge difference.
• Season in layers: Add a little salt at the onion stage and more at the end. This builds deeper flavor without accidentally overseasoning.
• Make it ahead: The soup base (without noodles) can be made up to 2 days ahead. Cook and add noodles when reheating to avoid mushy pasta.
• Pumpkin puree tip: Don't use pumpkin pie filling—it's sweetened and spiced, which will throw off the savory balance. Always get 100% pure pumpkin.
• Adjust thickness: If the soup is too thick after adding noodles, thin it with extra broth. If too thin, simmer a few minutes longer to reduce.
• Use a Dutch oven: The heavy bottom distributes heat evenly and prevents scorching. A large soup pot works too, but stir more frequently.

Variations and Substitutions

• Vegetarian Version: Omit chicken and use vegetable broth. Add 1 can of drained chickpeas or 2 cups of chopped mushrooms along with the onions for texture.
• Spicy Pumpkin Soup: Add 1/2 teaspoon red pepper flakes or a pinch of cayenne along with the garlic. It gives a nice warm kick against the creamy base.
• Spinach & Kale Boost: Stir in 3 cups of fresh spinach or chopped kale during the last 2 minutes of cooking. It wilts down nicely and adds nutrients.
• Cheesy Broccoli Twist: Add 1 cup of small broccoli florets along with the noodles. They’ll steam in the soup. Top with extra cheese.
• Sun-Dried Tomato Version: Stir in 1/4 cup of chopped sun-dried tomatoes (in oil, drained) with the broth for a tangy pop.
• Gluten-Free Adaptation: Use gluten-free lasagna noodles or any gluten-free short pasta. Check cooking times on the package.
• Dairy-Free Adaptation: Use unsweetened oat milk, vegan cream cheese (like Kite Hill), and nutritional yeast instead of Parmesan. The texture will be thinner but still comforting.

Storage and Reheating

Fridge

Let the soup cool completely, then store in an airtight container for up to 4 days. The noodles will absorb some liquid, so the soup will thicken. That’s normal!

Freezer

This soup freezes well for up to 3 months. For best results, freeze in portions without the noodles (if you plan ahead). Otherwise, freeze with noodles, understanding they’ll be softer upon reheating. Thaw overnight in the fridge.

Reheating

Reheat on the stovetop over medium-low heat, stirring occasionally. Add a splash of broth or milk to restore the creamy consistency. If the soup seems grainy (from dairy separation), a quick whisk over low heat usually brings it back. Microwave on medium power in 30-second bursts, stirring between each.

FAQ

Can I use already cooked chicken? Yes, add 2 cups of shredded rotisserie chicken in step 5 instead of cooking raw chicken. Simmer just to heat through.

Can I make this soup in a slow cooker? Yes. Sauté onions and garlic, then transfer to a slow cooker with broth, pumpkin, milk, cream cheese, seasonings, and uncooked chicken. Cook on low for 4-6 hours. Shred chicken, add broken lasagna noodles, and cook on high for 30-40 minutes until noodles are tender.

What can I use instead of pumpkin? Butternut squash puree is the best substitute. Steam and blend 1 medium squash until smooth. Carrot puree also works but tastes sweeter.

Can I make this dairy-free? Yes. Use unsweetened oat milk, dairy-free cream cheese, and nutritional yeast (2 tablespoons) for a cheesey flavor. Skip the heavy cream. The soup will be thinner but still tasty.

Is this soup gluten-free? If you use gluten-free lasagna noodles, yes. The rest of the ingredients are naturally gluten-free.

How do I keep the noodles from getting too soft? Cook the noodles separately and add them to individual servings. This is ideal for meal prep or if you want perfectly al dente noodles every time.

Can I freeze this soup? Yes, but for best texture, freeze the base without noodles. When ready to eat, thaw, reheat, and cook fresh noodles in the soup.

What goes well with this soup? Serve with crusty bread, a simple green salad, or garlic knots. A side of roasted broccoli also complements the creamy soup.

Can I skip the cream cheese? Yes, but the soup will be less creamy. Increase the Parmesan to 1 1/2 cups and stir in 1/4 cup of heavy cream for richness.
